    Product description

    The Interferential stimulator is a dual-channel electronic unit. It incorporates a digital display that indicates the operational modes and the output. It is equipped with an 8-bit microcomputer for controlling the system. The intensity, duration, frequency, and modulation of the electrical impulses can all be adjusted. The stimulator uses 4 electrodes producing deeper stimulation when compared to other types of electrical stimulation.

       IF-908 is the interferential stimulator (IF) device which is a battery-operated device that includes two controllable output channels. Amplitude, mode, and duration of the electrical impulses can be altered with the buttons or knobs. The biggest difference between TENS and IF is the rate. The pulse rate of IF is around 4000-4100 Hz which is much higher than TENS (2-150 Hz). This high-frequency stimulation can easily pass through the skin and reduce pain more effectively.

    IF-908 provides effective interferential stimulation treatment for the relief of chronic pain, especially for aching muscles of the back, arms, or legs. The controls are protected by a cover in order to prevent accidental changes to the settings. With 9 IF modes and premium quality adhesive electrodes, IF-908 provides you the highly effective nerve stimulation for pain relief and pain management.
